Atherinosoma microstoma (Günther 1861)

Anadromous. Fish that ascend rivers to spawn, as salmon and hilsa do. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.

Found in shallow coastal bays, estuaries and lakes ranging from pure fresh to salinities in excess of seawater (Ref. 9002). Occurs abundantly in in estuaries around eel-grass thickets, occasionally penetrating the lower freshwater reaches of rivers. Feeds on tiny crustaceans and insects. Breeds in spring (September to October). An annual species (living for only one year), dying shortly after spawning (Ref. 44894).
